I case you are still undecided about "pavers", consider real Georgia Red Clay Brick. may cost a tad more, but what a difference. "Fake" pavers are colored with a dye, (and are molded concrete, not fired brick), which, in our Florida intense sun will fade and in a few short years you could notice the fading, and be disappointed. You dont want to be one who mutters "If only I had known".
I put them in in 2000. All 6600 of them. Still the same color as when I installed. Their color of course, comes from natural minerals (iron, mostly). never fade in the sun.
I packed crushed shell- available in FL mostly anywhere. 5" deep. Good luck.
